SPM-D2-11 Series
Drop-In Successor to SPM-D11 Load Share Synchronizers
We understand the time-intensive nature of power generation projects and ensuring the longevity of components is a specific way we contribute to our customers’ success. We’ve supplied and supported the well-established SPM-D line of synchronizers for over 20 years. And, now, the new SPM-D2 with its state-of-the-art technology extends the life of your synchronizers as a drop in replacement for your SPM-D units.
The SPM-D2-11 is a microprocessor-based synchronizer designed for use on one- or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D2-11 synchronizer provides automatic frequency and phase and voltage matching using either analog or discrete output bias signals. It combines synchronizing for one circuit breaker, load and power factor control, or isochronous load sharing and generator protection. This synchronizer is applied to a wide range of prime movers and generators, as its control signals may be set to fit several types of gensets -- from fast-reacting diesel engines to soft-reacting gas turbines.
All SPM-D2 synchronizers are password protected and configurable either through HMI (as were the SPM-D units) or through the ToolKit configuration tool with USB connectivity.
Benefits include:
- Compatible with a wide range of governors, automatic voltage regulators, and circuit breakers
- True RMS voltage sensing for reduces susceptibility to harmonics
- Front face synchroscope for easy commissioning
- HMI programming and USB connectivity to Woodward ToolKit service tool
- Drop-in replacement for existing SPM-D11 synchronizers
